| Bioactivity | C-021 is a potent CC chemokine receptor-4 (CCR4) antagonist. C-021 potently inhibits functional chemotaxis in human and mouse with IC50s of 140 nM and 39 nM, respectively. C-021 effectively prevents human CCL22-derived [35S]GTPγS from binding to the receptor with an IC50 of 18 nM[1]. | ||||||||||||
| Invitro | The in vitro oxidative metabolic stability of C-021 (Compound 1b) is evaluated by measuring the rate of drug consumption in human liver microsomes (HML), thus providing intrinsic clearance values (CLint). C-021 exhibits CLint value of 17,377 mL/h/kg[1]. | ||||||||||||
| In Vivo | The potency of C-021 (Compound 1b) is evident after subcutaneous administration in the murine oxazolone-induced contact hypersensitivity test, a known model of acute skin inflammation. When C-021 is administered orally, however, very little inhibition is observed[1].C-021 (1 mg/kg; i.p.; daily; for 3 days) significantly less microgliosis in acute liver failuremice[2].
